Thread: Chisel Mortiser

hi dean. havent got the carbitec 1/2 hp chisel but have asimilar leda brand.
it is okay on softwoods but almost impossible to cut into h/wood, (unless i have the chisel set up incorrectly! can any one help?how far out of the bottom do you have the drill from the chisel?)
so it really depends how often you are going to use it. also the quality of the chisels are a facter as well, the points on the cheap ones tend to fold up after a while especially on aussie timbers.
so your probably going to be loking at spending 80 -100 $ on a good quality chisel!
hope ive answered your questions and not put you off, & i hope someone answers mine.
seeyasoon mik.

Hi Dean, I also use a generic Taiwanese model that hasn't let me down yet.

Sorry cannot comment on the Carba -Tec model but suspect it may be out of Taiwan where they source some of their machinery.

Mik I have bought a special honing stone for tidying up the profile inside the chisel and provided that the cutting external sides of the chisel(s) are kept polished to reduce friction then the task becomes easier.

I set a 2c piece as a gap adjustment to the quill/chisel which should give you a slight protrusion of your drill from the chisel.
It is important to note that the chisel in it's rotation and bite must release wood fibre tension to allow the chisel to function as it is intended.

Cheers

John, is your model a 1/2HP model? and how does it go on hardwoods?

I would mostly use it on pine, but would be also handy for the occassional hardwood adventure.

BTW, the model I was looking at from carbatec is no longer being sold by them apparently...they have a new replacement model in, but not up on their website yet.

Dean

Dean ,the model I have is one with a W.M.S name on (Woodworking Machinery Specialists) which I think are in Melbourne.
The model is 3/4 HP one and not the size you are looking for but I have no problems in Jarrah as I do a series of shallow bites rather than plunging thru each time.
Hope this helps.
Cheers

I have in the past month bought a Carbatec Morticer. It is the new style morticer as the old type is no longer available. It resembles the delta, in terms of the motorsize and shape. I have used it a few times and have found it to be good and quite acceptable in both soft and hardwoods. Although I would say that the quality of the mortice chisels(not included) from china are quite poor quality, and the machine will perform as good as the quality chisels you put into it. Also It is a 1/2 inch morticer, which should not affect your purchase as most morticers in this category are the same.

P.S Also comes with a drill chuck.

thanks john, i will get one of those stones from mik int. next week and try it .
i aint going into the shed this w/end, work tomorow & sunday 39 too hot for this chump.
i think i have the drill and chisel too close.
seeyasoon mik.

I am now looking at the Carbatec and Timbecon morticer (virtually identical) and also the Jet version which is around $100 more expensive, does anyone have the Jet version and is it worth the extra cost. all other specs seem very similar.

Tony how have you gone with your Carbatec machine in the last few months?

Cheers

Why use a chisel mortiser at all? I think router-based morticing machines or a hand-held router with a morticing jig are far more satisfactory. It only takes a couple of minutes to round a tenon to fit a routed mortice.

I have the Delta, and after working out how to correctly fit the drill and chisel in relation to each other, I have cut many mortises with no problem at all. Having good, sharp chisels/drills is absolutely essential.

The advantage of a mortiser over a router is mostly in the depth of cut.

Another advantage - ease of setup - you can see what you are doing.

And a hell of a lot quieter!!

I have a Delta machine. I bought a few higher quality chisels when I purchasedit. It goes well, made a bed out of Bartu (Indonesian hardwood) and cut about 80 mortises for slats, took a while but did it without any problems.

Sorry I took so long to post. But I have used the machine for 350 mortices that I know. The only problem is the cheap chinese chisels, and the (thingy) the same thing used to holdup the boot in liftback cars? went and I got it replaced under duress by Carbatec. The motor is quiet. I do however like the Delta model a little better because they use slide up and down on gears. Carbatec a few months back had the Delta out cheap, maybee you could give them a call and haggle. I suggest that when not using the chisel morticer, I lock the depth setting so that there is no pressure on that ram.
