Question about Delta TP305 12 - 1/2" Portable Planer

1 Answer

Why does my TP305 takes off more material at the beginning and at the end of the board than it does in the middle? It is a considerable amount. I've cleaned and tightened everything I can.

This is called snipe and it is a common problem. There are two feed rollers, one before and one after the cutter. When one of them drops off the board, the cutter drops down a little. You can minimize this by taking very light cuts, even making your final cut a second pass without lowering the cutter at all. You can also use a scrap piece of wood immediately preceding and following your good piece (it has to be long enough) And of course you can start with your good piece over-length. Good luck.

Mahindra 6500 will not take off hardly in high gear. In low gear it works fine until going up a steep hill. Smells a little like burning plastic when this happens. Is ther an adjustment.

From your description it would seem the clutch friction material is worn out and needs replacing, though it is possible the clutch spring (diaphragm) has become weak.

There might be an adjustment but I have no knowledge of that model. Mechanically (cable) operated clutches mostly have an adjustment to maintain a small amount of clearance (free play) in the pedal operation and also a very few of the older hydraulically operated systems but mostly these are self-adjusting.

A healthy clutch is designed to transmit the full engine torque with a good margin extra, though it must be remembered even a healthy clutch when it is overheated can begin to slip. As a clutch wears and becomes less efficient it is important to be considerate to it and keep it cool by driving in a manner that is less stressful for it and by not allowing it to slip.

If the clutch is not self-adjusting, adjustment should be attended to during routine maintenance or when needed. Even if your car has an adjustment I think it is unlikely to help...

You get sniping with all planers and it will always be the length from the cutter head to the second feed roller. Until the board goes under the second roller it is almost impossible to feed it through and not get some sniping. The same applies to the outfeed side also. Better made (more expensive) planers, table extensions and holding up on the end of the board until the other end is under the second feed roller will reduce sniping somewhat but you'll always have some sniping.

My tp305 removes more wood on the left than on the right. There does'nt seem to be anmy way to adjust this, is there?

These portable planers have a not-negligible amount of flex to them, and you will probably remove a bit of wood even if you run the board through a second time on the same side. But try this to determine if you would want to try to reset the blade height---- run two narrow pieces simultaneously on the left and right. Check the thickness before and after with calipers or something precise. Then switch the two boards and run them again without changing the setting. If it is only cutting on one side, and the thickness was significantly different before the second run, then you might want to adjust the blades in the cutter-head.
Good luck.

When feeding a board say about 8 ' wide into the planer it comes out the other end crooked at about 20 degrees.what can be causing this.The model is Delta TP 305 , 12 1/2".

There are a possible number of causes, few of which can be adjusted away.
However, check to make sure the base of the planer, the table under the board is clean and free of pitch and scratches or debris that could interfere with the smooth passage of the board. I use Trewax or some other paste wax on mine to facilitate the board's passage.
You may have a feed roller that is tighter on one side than another, i.e. it is closer to the table on one end than the other end of the roller. It's unlikely there's anything you can do about this, even if you were to make the appropriate hardwood block needed to measure the roller's height at different positions across the table. Small portable planers are prone to this, and often your only recourse is to hold the board straight as it feeds through the machine, by exerting gradual pressure on the side against which it twists.
Finally,it could be the boards that you're feeding into the machine are not flat or have non-parrallel faces to begin with, so the knives of the planer are forced to take a deeper cut off one side of the board. Take a lighter pass and see if the board runs straight. You might be hogging too much off for the planer.
Or the knives could be dull, or knicked, or improperly adjusted and not parrallel to the cutterhead.
But this can be a problem even with industrial quality machines. Normally we just hold the board straight and move on the the jointer or the table saw. It's frustrating behavior, but you can only spend so much time tweaking machines, and then you have to get on with the woodworking.
Hope that helps somehow.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

Shut down in the middle of sewing and will not turn back on.

Was it tired? The bobbin case is locked in place, because of tread or lint.
The "hook" will not move. Take the bobbin unit apart and clean and oil the hook (yes, oil, just a Q-tip amount).

Keep on Sewing

DX6440 LCD screen is Black

As I suspected, the flexible circuit board which connects the fluorescent back light to the power source was severed. Although it didn't appear broken at first, the LCD came on as I poked the flex board. I removed a small amount of insulation and reconnected the two copper leads. Problem solved.
The flex board I speak of is an amber colored ribbon; it can withstand high temperatures and is quite durable. There are two copper leads embedded in the ribbon. One end of the ribbon is sealed within the LCD, the other end terminates in a locking surface mount connector. You can unlock the connector by pulling back on the little brown latch. If you have a severed flex board, be extremely careful in repairing the connection. Once you begin removing the amber coating, it becomes fragile.
