I borrowed a 2-3 year old Delta HC Mortiser from a buddy. He’s hardly ever used it. I’ve used it twice, once for a set of 12 chairs and another set of 14. Lots of tough mortises since they’re Stickley repros in QSWO. Anyway Saturday doing the last 144 mortises (the ‘easy’ 1/4″ers) the hydraulic strut puked it’s oil, the dovetail gib on the head loosened up and the keyway on the plunger gear stripped. The set screw wasn’t loose so either the key and/or the keyway in the gear and shaft deformed so badly that there’s an inch or two of slop at the end of the handle. With this much damage I don’t think I can get it apart without risking the cast iron housing. It’s probably out of warranty, but this is ridiculous. I’m going to take it to my local rep and see what happens. Is this a known problem?
Also I’ve gone through several hollow chisels. Snapped 1/4″ and 3/8″ bits and split a 1/4″ chisel. Tried the ‘dime’ trick to gap the bit and that’s way too sloppy. Developing slop in the head ways may of played a part, but while where on the subject, what’s the best brand of hollow chisel, Fisch (Austria) or ???

Well, I'm not very good at writing "Dear John" letters, but I'll have to give it a try. Although I have not encountered the type of problem you're having with the gears, I can speak on behalf of the Delta HC mortiser. I had purchased the same benchtop model you have been using some 2-3 years ago. Before, I was using routers and regular hand chisels to cut my mortises. Way to slow and tedious. I had dreams of Stickley dancing in my head and thought that a new Delta mortiser was just the ticket. On the very first day of use, I had snapped three seperate bits while attempting to cut mortises in red oak and maple. The mortises that I did manage to cut were sloppy, out of allignment, and simply a bear to manage. I had sold the machine within 24 hrs. What a let-down. John, my suggestion is that you check out the Garret-Wade catalog and look at some of the Multico selections. Pricey, but they'll deliver good results. Also, Powermatic has that nifty floor model out now. Looks BEEFY. Did you try Wilke Machinery or General Machinery? Both produce mortisers and both have websites. As for your friend's Delta, the charge to repair it may approach the price of a new one.
Best of luck.

You are not alone -
I HAD the same type of machine and the elbow casting that holds the
arm used for plunging broke - then the fence brkt. that goes thru
the main support snapped - then the hold down casting snapped off -
I'm a chairmaker and mortiserer are everything to me - so I took
the machine back to the dealer that I bought it from and made ####deal - trading the Delta for the Jet bench top model. List price
minus the purchase price I paid for the Delta. The Jet unit worked
great and I'm very happy with it - that is untill I bought
the Powermatic # 719 and now I live in dreamland - daily.
Check with Delta- I'm sure there are others that have had casting
failures on this machine.
Hope this helps.

Jeeze! I guess it could be worse. I'm not sold on the Jet nor the Fisch either. I've used a Multico PM10 (?) and the hold down and the depth stop don't stay put. I want the cross slide table which the bigger Mulitco (PM20?) has. What others did you checkout before getting the Powermatic? The crappy part part is that I'm gonna have to pay to fix my buddy's Delta and then go buy a mortiser of my own. John O'Connell - JKO Handcrafted Woodworking

The Powermatic 719 was not on the market at the time I was
having all of the problems with the Delta - so the Jet was
the next best thing at the time. I was in the beginning of
a small run of chairs and needed something RIGHT THEN.
For the most part I try to buy equipment from local sources
so when things go wrong I can actually put my hands on someone(G)
and get replacement parts or repairs done quickly. I'm at
the mortiser every day and use a range of bits from 1/4" thru
3/4". The Powermatic has served me well so far and I just
don't have any complaints at all on this machine. I don't
have any info on the manufactor you mentioned but Garrett
Wade is a good supplier and I've had no problems with them in
the past. My only drawback would be the fact that they are not
local.
