mistermikev Posted June 22, 2020 Report Share Posted June 22, 2020 so this is a jig I built for adding a taper to my stock for a lam neck. Haven't sent her thru yet, and admittedly nervous about sending metal thru a planer. test me? have I thought of everything? well I have some lock nuts on the bolts that are holding down force on the top board... so that should they vibrate the bolts won't end up dropping down into the planer. Just have the pieces secured with a big long strip of carpet tape. I think once the down force has 'em they aren't going to move anyway but side to side anyway. thoughts? i mike v being of sound body and mind hereby admit my last will and testament...

Bizman62 Posted June 22, 2020 Report Share Posted June 22, 2020 That looks solid. However, if I read the picture right, do the long bolts secured with nyloc nuts roll freely? If so, a pair of nuts to stop the bolts from screwing through the T-nuts might be recommendable: 1 Quote Link to comment Share on other sites More sharing options...

I could tighten up the lock nuts and that would prevent. also thought about adding lock nuts to the 4 height bolts to prevent vibrations from spinning them. again, there is some resistance there so I don't think it will but better safe than sorry.

Bizman62 Posted June 22, 2020 Report Share Posted June 22, 2020 Yet another question about the same bolts: Are they for adjusting the height of the upper board? If so, the T-nuts are on the wrong side as pressure can push them off the board. 1 Quote Link to comment Share on other sites More sharing options...

I am going to add additional lock nuts to the height adjust bolts at end and center just to lock them in better but I didn't have any problems. here's the result: not sure if the seperation there at the end is from the wood 'moving' as it was just cut... or if I had a subtle amount of bow in my jig... but I can clamp it all closed just using my hands so... should be good.

I saw the other bolts as well but didn't know which way they worked. We're going to see some spectacular necks pretty soon, aren't we?

I appreciate your input on it biz. Quote Link to comment Share on other sites More sharing options...
